Patent JP-H01238209-A (JP)
Title: Optical reception circuit
Inventor: NAITO SEIGO
IPC: H03F3/50
Filed: 1988-03-18
Abstract: PURPOSE:To prevent a saturation at the time of writing and to normally read a signal by controlling the potential of a control input terminal connected to the common base terminal of plural light reception elements and changing the current of a diode connected to the common base terminal. CONSTITUTION:Since transistors(Tr) Q3, Q4, the diode Q5 constitute a current mirror, a collector current equal to a current passing through the diode Q5 is caused to pass to the Tr Q3, Q4. Accordingly, the potential of the control input terminal A is changed to control the current passing through the diode D5, thereby, a part of a current passed from the respective light receiving elements 1a, 1b is bypassed or the quantity of a bypass current can be controlled. When a light input is large, the potential of the terminal A is raised to increase the current passing through the diode D5, and then, the current passing through the Tr Q3, Q4 is increased and a signal current passing to the light receiving elements 1a, 1b is bypassed. Thereby, the saturation of receiving circuits 2, 3 by a direct current light is prevented.

Title: Production of coated decorative board having grain of natural wood with three-dimensional profundity
Inventor: DAITOKU TAKESHI
IPC: B05D5/06
Filed: 1980-05-16
Abstract: PURPOSE: To obtain a coated decorative board having the grain of natural wood and three-dimensional profundity, by making wood surface rugged under pressure with heating during the complete curing of a semicured gelatinous paint film formed on the wood surface.  
     CONSTITUTION: A curing resin paint is applied onto the surface of wood board 1 in the first step. The curing resin paint is, for instance, an unsaturated polyester resin dissolved in a solution of a polymerizable unsaturated monomer such as styrene or the like mixed with a polymerization initiator and optionally a polyisocyanate crosslinking agent. The paint film is brought into a semicured gelatinous state by heat, light or the like in the second step. At this time, the paint film may leave slight tackiness or no tackiness at all. In the third step, the paint film 4 formed in the former step is completely cured under pressure while heating with hot press 5, 6, for instance. In this case, the film 4 is fluidized but does not easily penetrate into the board 1 because the film 4 has very strong viscoelasticity in the gelatinous state. Consequently, the pressure applied onto the film 4 is transferred to the surface of the board 1, so that a softer spring wood part 2 having a lower fiber density, as compared with a harder autumn wood part 3 having a higher fiber density, is compressed  to form concavities 7.
